Abstract

The present invention relates shortly to an angular gear (1) for use in venetian blinds for angular adjustment of the venetian blind laths from a place beside the venetian blind. The angular gear (1) consists of three parts, a gear housing (2), a shaft (3) provided with a helical gear (10), and a pinion (4), the shaft (3) being provided with or constituting an operating means and a pinion (4) meshing with the helical gear (10) being anchored to the shaft suspending the venetian blind laths, by the aid of ladder bands attached to the shaft. The shaft (3) is provided with at least one bearing portion of circular cross section and this bearing portion cooperates with a complementary bearing portion in the gear housing (2). In connection to the bearing portion or portions there is a neck portion (14) in the shaft, and in the housing (2) there is at least one tongue (6) having a hook-like means which by the aid of the tongue is biassed to protrude into the neck portion and gear which maintains the shaft (3) in axial position in the gear housing (2).
